IMPROVED MBT-HOD OF GARBURETTING GAS.

T0 ALL WIIOM IT MAY CONGERN:

Be it known that I, CY'RUS M. WILLIAMS, of the city, county', and State of New York, have invented a new and useful improvement in Method of Carburetting Gas; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, `forming a. port of .this specification.

` The object of this invention is to provide for the uniform carburization of coal gas in large volumes before its distribution to the service mains; undconsists, for this purpose, of the application of the hydro-carbon liquids to the volume of gas when in the holder, by such devices` as will thoroughly incorporate with the gas a proportion of the vapors-of a. volatile hydro-carbon, thus addingr toits photometric value. In the ordinary methods and appliancesfor carburetting, the hydro-carbon vapor is added tothe gas after it has passed through the metre on the premises of the consumer, necessarily involving a large number of diii'erent forms of apparatus to suit` the various conditions, and a consequent increase in the care and attention to keep it in, proper Working order. All this may be more perfectly accomplished before the distribution of the gas, with u. corresponding diminution of labor. There are many forms of apparatus which may be used to accomplish this result, the most obvious' and simple method boing to introducel a quantity of hydro-carbon liquid upon thesurfaco of the Water in the tank Iinside the holder, where it vrill float ou the surface of tliewater, and by its evaporization mix ,with the volume of gas in the holder, the hydro-carbon being added from time to time, as required.- But I prefer to use the device shown in the drawing, by which the hydro-carbon liquid is divided into fine particles and showered through the volume of gas, p'crmelating it thoroughly; the remaining liquid falling through any l arburctting brous substance to prolong thedivision of the hydro-carbon iluid o1' not, on to the surface of the water, and being evaporated as in the first method. he carbon spirit may be contained in a reservoir-placed at a sufficient height above the holder to descend by its weight, being connected with the holder by a flexible tube or sliding pipes to compensate for the rise and fall oi' the holder,thc motion of which may also be used to `work any automatic device or apparatus necessary or desirable to regulate and supply the proper quantity and regular ilow of the hydro-carbon liquid.; or by means of a force-pump intermittent'showers of spray'may be injected, accomplishing the same result. It may be found desirable to suspend in the holder some fibrous mate- 'rial for the purpose of increasing the Vevaporating surfaces, and arranged so as to receive the dropping of the shower of hydro-carbon. The temperatur-e of the water in the holder maybe regulated as desired. For this purpose the waste heat from the furnace-or steam pipes may be used for the purpose of maintaining a uniform temperature of the water in the tank, thus keeping the evaporation of the hydro-carbon under control.

The drawing indicates a vertical section of the apparatus used.

A represents the gas-holder. B the tank fc1.Water. C is the inlet, and D the outlet for gas. .E is the sprinkler for'the purpose of distributing the hydro-carbon. F is the valve by which the supply of hydro-carbon is regulated. G, flexible tubing connecting the supply tank with the holder. E, supply tank.

I have described the means of carburetting the gas in the gasometer or holder, but it is obvious that it may be carburetted by similar means in the hydraulic main, the scrubber, o1'A in any of the puriers. I do not, therefore, limit myself to the precise devices herein shown and described, nor to carburetting in the gas-holder; but what I dol claim as my invention, and desire to secure by Letters Patent, is-

1. Carburetting illuminating gas by mixing or combining with it the vapors of volatilechydro-carbons before it is introduced into the service mains for distribution, substantially as described.

2. I also claim the devi-ces herein shown and described, for carburetting gas in the holder before its distributionto the servico mains.
